The nurse is explaining to the daughter of a client how pain is perceived by the individual. The nurse tells the client's daughter that which of the following is considered the main relay station for sensory information related to pain?
1. Cerebral cortex
2. Limbic system
3. Thalamus
4. Reticular system
3. Thalamus
Rationale:
The thalamus is the main relay station for sensory information. Pain information is then transmitted to the cerebral cortex as well as the reticular and limbic system for the processing and interpretation of pain. The cerebral cortex is the second step in processing pain stimuli. The transmission of pain moves through the limbic system after the thalamus. Transmission of pain impulses occurs in the reticular system after traveling though the thalamus as the main relay station.
